CHARLES M. HOWELL, OF ANDOVER, NEW JERSEY.

Letters Patent No. 99,194, dated January 25, 1870.

To all when). it may concern.-

Be it known that I, CHARLES M. HOWELL, of Andover, inthe 'county of Sussex, and State of New J ersey, have invented a new and improved Wagon-Brake; and I do hereby declare that the following is a full, clear, and exact'description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawings, forming part of this specification.

Myinvention relates to wagon-brakes; and consists in the peculiar construction and arrangement of parts upon the wagon, so as to secure great strength, and prevent any racking effect upon the under portions of thewagon. j

Figure 1 is a side elevation of a wagon provided with my improved brake, and

Figure-2 is a plan of the bottom of the same.

Similar letters of reference indicate corresponding parts.

A-are the brake-shoes, suspended in front of the hind wheels, on thearms B,of the shafts 0, supported inthe same axis, in suitable hearings on the bottom of the box or frame.

The arms B, projecting downward from the shafts, are connected to the levers E, by the rods F. These levers are pivoted to the rear axle, so that the direction of the forces imparted by them to the axle, and ,by the shoes to the wheels, will oppose and neutralize each other through the wheels and the axles.

The long arms of these levers are connected, by rods H, to an evener, I, pivoted in the end of a rod, K, connected to the arm L, of an oscillating shaft, M, suspended from the bolster or front part of the wagonbox, and provided with a hand-lever, N, at one end,v

rising'up at the side of the box, for operation by the brakeman, to draw the brakes down upon the wheels, pushing it forward.

This arrangement is very simple and strong, and has less strain and damaging efl'ect on the box than others, by reason of the connection of the levers E on the hind axle, whereby the strains on the wheel and axle counteract each other.

By arranging the shaft 0 in two parts, and connecting the levers to the evener I, which is capable of swinging forward or back at either end, the pressure will be equal. on each wheel, although there may be variations in the diameters.

Having thus described my invention,

' I claim as new, and desire to secure by Letters Patent- Operating the brake-shoes A A by means of a vibrating shaft, M, having arm L thereon, rod K, evener I, connecting-rods H H, levers E, rods F, and shafts 0, all constructed, arranged, and operated in the manner described.

' CHARLES M. HOWELL.
